Chenopodium album L. (family Chenopodiaceae), a noxious weed globally distributed that is a large genus commonly known as white goosefoot and fat-hen, melde, pigweed, lamb’s quarters, lambsquarters or local names. It has nutritious value and more than thirteen compounds accounted and subsistence food crop; seed are processed into flour for pancakes and bread. It is boiled and mixed with other ingredients to make a kind of gruel, or is roasted and ground for porridge or also used for preparing fermented and alcoholic beverages. Medicinally it is used to cure the diseases of blood, heart, spleen, and eye and in biliousness conditions, anti-cancer property, antipruritic and antinociceptive activities. The plant traditionally used as a laxative, anthelmintic, blood-purifier, antiscorbutic, appetizer, aphrodisiac and tonic. It is nutraceutical food, an alternative source for nutrients. The plant contains essential oils, besides alkaloids, trigonelline, chenopodine, potassium and vitamin C, total phenol flavonoid glycosides (quercetin, rutin, and kaempferol). The major class of phytoconstituents includes nonpolar lipid, phenols, and lignins, alkaloids, flavonoids, glycosides and...

Amino acids are biologically active substances, and a number of them are essential for living beings. Amino acids are found in living cells as well as in body fluids of higher animals, in amounts, which vary according to the tissue and particular amino acid. Amino acid analysis refers to the methodology used to determine the amino acid composition or content of proteins, peptides, and other pharmaceutical preparations. Proteins and peptides are macromolecules consisting of covalently bonded amino acid residues organized as a linear polymer. The sequence of the amino acids in a protein or peptide determines the properties of the molecule. Proteins are considered large molecules that commonly exist as folded structures with a specific conformation, while peptides are smaller and may consist of only a few amino acids. Amino acid analysis can be used to quantify protein and peptides, to determine the identity of proteins or peptides based on their amino acid composition, to support protein and peptide structure analysis, to evaluate fragmentation strategies for peptide mapping, and...

Dementia is a progressive neurological disease of the brain. It demolishes the vital brain cells, causing trouble with memory, thinking, and behavior, brutal enough to affect work, lifelong hobbies, and social life. Recognized factors in dementia include acetylcholine deficiency, free radicals, and inflammation of the brain tissue. Since, the drugs and natural remedies have been prescribed to enhance the memory and protect the memory functioning in dementia people. The traditional herbal medicine, numerous plants have been used to treat age-related cognitive disorders. The use of herbs to treat ailments would later form a large part of Ayurveda. In the first millennium BCE, there emerges in post-Vedic India the traditional medicine system known as Ayurveda, meaning the “complete knowledge for long life”. According to the compendium of Charaka, the Charakasamhita health and disease are not predetermined and life may be prolonged by human effort. The compendium of Suśruta, they defines the purpose of medicine to cure the diseases of the sick, protect the healthy, and to prolong life. Most remarkable...

In this review, the current knowledge on the phytochemistry and pharmacology of Piper betle (betel), Piper sarmentosum (wild pepper) and Piper caninum (wild betel) is updated with some description of their botany and uses. Leaves of P. betle contain polyphenols, alkaloids, and essential oils, and display broad-spectrum antibacterial activity, substantial quorum sensing inhibition and tyrosinase enhancement activity. They also possess anti-malarial, anti-diabetic, anti-inflammatory, antinociceptive, hypoglycaemic, neuro-protective and hepatoprotective properties. Leaves of P. sarmentosum contain phenylpropanoids, phenylpropanoyl amides, dihydroxyflavone, and essential oils. Wild pepper displays a wide array of pharmacological properties including antioxidant, antibacterial, antifungal, anti-amoebic, anti-dengue, anti-tuberculosis, cytotoxic, antiplasmodial, neuromuscular-blocking, antinociceptive, anti-inflammatory, hypoglycaemic, anti-atherosclerosis and anti-osteoporosis activities. Leaves of P. caninum contain phenolic compounds, alkaloids, and essential oils. Pharma-cological properties of wild betel include antioxidant, antibacterial, antifungal, DNA-damaging, DNA strand-scission, and anticancer activities. All three Piper species reviewed possess pharmacological properties, which confer their traditional and contemporary uses as food and herbal...

As life expectancy increases, malfunction or loss of tissue caused by injury or disease leads to reduced quality of life in many patients at significant socioeconomic cost. Bone disorders are of significant concern due to the increase in the median age of our population. Traditionally, bone grafts have been used to restore damaged bone. Even though major progress has been made in the field of bone tissue engineering, present therapies, such as bone grafts still have limitations. Current research on biodegradable polymers is emerging, combining these structures with osteogenic cells, as an alternative to autologous bone grafts. Different types of biodegradable materials have been proposed for the preparation of three-dimensional porous scaffolds for bone tissue engineering. Among them, natural polymers are one of the most attractive options, mainly due to their similarities with the extracellular matrix, chemical versatility, good biological performance, and inherent cellular interactions. Also, synthetic biomaterials are now being used as bone graft substitutes. These biomaterials were initially selected for structural restoration based on their biomechanical properties....
